I've actually had the opposite problem, I have yet to make a habit of saving my noscript (now umatrix) settings, so any time-saving of eliminating slow scripts is wasted refreshing it three times trying to figure out which cdn is the important one; and trying to selectively enable the scripts of a video streaming site is even worse. Still worth having it though, especially when you go to traditionally sketchy download sites and see it have a cleaner UI than the apple homepage with just a single download button.
